Description
- The present application is a continuation of International Application No. PCT/JP2020/046629, filed on Dec. 15, 2020, and based upon and claims the benefit of priority from Japanese Patent Application No. 2019-229046, filed on Dec. 19, 2019, the entire contents of which are incorporated herein by reference.
- The present application relates to a connector.
- There has been proposed a connector configured to allow a terminal received in a connector housing, to be released by a terminal extracting tool (see Japanese Unexamined Patent Application Publication No. 2002-231362).
- A conventional connector includes a connector housing and a terminal. The connector housing includes a plurality of terminal receiving chambers, a plurality of tool insertion holes, and a plurality of lances. Each terminal receiving chamber is separated from an adjacent terminal receiving chamber by each of side walls disposed on both sides thereof. The terminal receiving chambers are arranged in parallel. Each tool insertion hole is formed to each side wall. Each lance is locked to a terminal received in each terminal receiving chamber.
- Each lance is provided with a pair of lance unlock ribs protruding in adjacent tool insertion holes. Two lance unlock ribs are placed side by side in each tool insertion hole located at the center side with respect to both ends in a parallel direction of the terminal receiving chambers. One of the two lance unlock ribs is one of a pair of lance unlock ribs provided to one of adjacent lances. The other of the two lance unlock ribs is one of a pair of lance unlock ribs provided to the other of adjacent lances. By placing two lance unlock ribs in one tool insertion hole, the housing connector is made more compact in a with direction thereof.
- Next, a terminal release operation will be described. A pair of insertion rod portions of the terminal extracting tool is inserted into adjacent tool insertion holes with respect to a terminal receiving chamber in which a terminal to be released is received. Lifting a pair of lance unlock ribs, which is placed in the adjacent tool insertion holes, with the pair of insertion rod portions, causes the lance to be in a terminal release state. In this state, the terminal to be released is released from the connector housing.
- As described above, two lance unlock ribs are placed side by side in each tool insertion hole located at the center side with respect to the both ends in the parallel direction of the terminal receiving chambers. In a process of lifting a pair of lance unlock ribs with a pair of insertion rod portions, this configuration prevents the pair of insertion rod portions from moving in a direction away from the pair of lance unlock ribs (opening direction).
- However, in each of tool insertion holes located at the both ends in the parallel direction of the terminal receiving chambers, only one lance unlock rib is placed. Due to this configuration, in a process of lifting a pair of lance unlock ribs with a pair of insertion rod portions, the pair of insertion rod portions can move in a direction away from the pair of lance unlock ribs. In a case where the pair of insertion rod portions moves in the direction away from the pair of lance unlock ribs, there is a possibility that the pair of insertion rod portions cannot lift the pair of lance unlock ribs.
- It is an object of the present application to provide a connector capable of reliably lift a lance unlock rib placed in a tool insertion hole located at each of ends in a parallel direction of a plurality of terminal receiving chambers, with a terminal extracting tool.
- According to the present application, there is provided a connector including: a plurality of terminal receiving chambers arranged in parallel, a plurality of first tool insertion holes, a plurality of second tool insertion holes, a plurality of lances, and a plurality of pairs of lance unlock ribs. Each terminal receiving chamber is separated from an adjacent terminal receiving chamber by each of side walls disposed on both sides thereof. Each first tool insertion hole is formed to each of side walls excluding side walls located at ends in a parallel direction of the plurality of terminal receiving chambers. Each second tool insertion hole is formed to a side wall located at each of the ends in the parallel direction of the plurality of terminal receiving chambers. Each lance is to be locked to a terminal received in each terminal receiving chamber, and capable of moving toward a terminal unlocking direction by elastic deformation thereof. Each pair of lance unlock ribs is provided to each lance, and protrudes in the first tool insertion holes adjacent to each other or in the first tool insertion hole and the second tool insertion hole adjacent to each other. Two lance unlock ribs are placed side by side in each first tool insertion hole. One of the two lance unlock ribs is one of a pair of lance unlock ribs provided to one of adjacent lances. The other of the two lance unlock ribs is one of a pair of lance unlock ribs provided the other of adjacent lances. A lance unlock rib and a tool pressing rib are placed side by side in each second tool insertion hole. The lance unlock rib is one of a pair of lance unlock ribs provided to a lance located at each of the ends in the parallel direction of the plurality of terminal receiving chambers. The tool pressing rib is provided to a side surface of the each second tool insertion hole, and protrudes in the each second tool insertion hole. A terminal extracting tool is capable of being inserted in the first tool insertion holes adjacent to each other or in the first tool insertion hole and the second tool insertion hole adjacent to each other.
- The tool pressing rib may be mounted along an insertion direction of the terminal extracting tool in the each second tool insertion hole.
- The tool pressing rib may be mounted at a position where the tool pressing rib faces the lance unlock rib in the each second tool insertion hole.
- According to the present application, there can be provided a connector capable of reliably lift a lance unlock rib placed in a tool insertion hole located at each of ends in a parallel direction of a plurality of terminal receiving chambers, with a tool extracting tool.

The insertion hole pick-upsurface 26 is formed in a tapered shape and provided on a side surface opposite to the side surface on which the adjacentlance releasing surface 24 is provided. In a case where the leading edge region of theinsertion hole portion 22 is shifted from an opening position of the firsttool insertion hole 6 or the secondtool insertion hole 6A, the insertion hole pick-upsurface 26 guides the leading edge region of the insertion rodeportion 22 in the firsttool insertion hole 6 or the secondtool insertion hole 6A. - Next, a release operation of the terminal 10 will be described. First, in a situation where the terminal 10 to be released from the
connector housing 2 is received in eachterminal receiving chamber 5 excluding theterminal receiving chambers terminal receiving chambers 5, the release operation of the terminal 10 will be described. - The
insertion rod portions tool 20 are inserted in the first tool insertion holes 6, 6 adjacent to theterminal receiving chamber 5 in which the terminal 10 to be released is received, respectively. As insertion of theinsertion rod portions insertion rod portions lance unlock ribs lance 7 that is locked to the terminal 10 to be released. As the insertion of theinsertion rod portions insertion rod portions lance unlock ribs - As insertion of the
insertion rod portions lance releasing surfaces insertion rod portions lance unlock ribs lance unlock ribs lance unlock ribs lance unlock ribs lance unlock ribs lance unlock ribs insertion rod portions - Even if the
insertion rod portions insertion rod portions lance unlock ribs lance unlock ribs lance releasing surfaces insertion rod portions lance unlock ribs lance unlock ribs - In a process of inserting the
insertion rod portions insertion rod portions lance unlock ribs lance unlock ribs lance releasing surfaces insertion rod portions lance unlock ribs insertion rod portions lance unlock ribs - With this configuration, the
insertion rod portions lance 7 to a terminal release position by lifting only thelance unlock ribs lance unlock ribs connector housing 2. - Next, in a situation where the terminal 10 to be released from the
connector housing 2 is received in theterminal receiving chamber 5 located on the end in the parallel direction D of the plurality ofterminal receiving chambers 5, the release operation of the terminal 10 will be described. In this case, theinsertion rod portions tool 20 are inserted in the secondtool insertion hole 6A located on the end in the parallel direction D of the plurality ofterminal receiving chambers 5 and the firsttool insertion hole 6 adjacent to the secondtool insertion hole 6A, respectively. - By the above-described operation, the

insertion rod portion 22 is inserted in the secondtool insertion hole 6A, the lance lifting surfaces 23 of theinsertion rod portion 22 firstly enters below thelance unlock rib 8 to be unlocked which is provided on one side of thelance 7 that is locked to the terminal 10 to be released, as illustrated inFIG. 7A andFIG. 7B . As illustrated inFIG. 8A andFIG. 8B , as the insertion of theinsertion rod portion 22 proceeds, thelance lifting surface 23 of theinsertion rod portion 22 gradually lifts thelance unlock rib 8 to be unlocked. - If the
insertion rod portion 22 is inserted in the secondtool insertion hole 6A in a situation where theinsertion rod portion 22 is opened from a normal position (in a situation where it is opened toward a side of thetool pressing rib 9 adjacent to thelance unlock rib 8 to be unlocked), the adjacentlance releasing surface 24 contacts thetool pressing rib 9 adjacent to thelance unlock rib 8 to be unlocked, and receives a reaction force from thetool pressing rib 9. Thereby, theinsertion rod portion 22 is returned to the normal position, which reliably lifts thelance unlock rib 8 to be unlocked. - After contacting the adjacent
lance releasing surface 24 of theinsertion rod portion 22, thetool pressing rib 9 contacts the toolopening prevention surface 25 of theinsertion rod portion 22. Thereby, the end part of theinsertion rod portion 22 is prevented from moving in a direction away from thelance unlock rib 8 to be unlocked. Therefore, as illustrated inFIG. 9A andFIG. 9B , theinsertion rod portion 22 can keep a state where thelance unlock rib 8 to be unlocked is lifted to the lance unlock position. - With this configuration, the
insertion rod portions lance 7 to the terminal release position by lifting only thelance unlock ribs lance unlock ribs connector housing 2. - Thus, a connector 1 includes the plurality of
terminal receiving chambers 5 arranged in parallel, the plurality of first tool insertion holes 6, the plurality of second tool insertion holes 6A, the plurality oflances 7, and the plurality of pairs oflance unlock ribs terminal receiving chamber 5 is separated from the adjacentterminal receiving chamber 5 by each of theside walls tool insertion hole 6 is formed to each ofside walls 3 excluding theside walls 3 located at ends in the parallel direction of the plurality ofterminal receiving chambers 5. Each secondtool insertion hole 6A is formed to theside wall 3 located at each of the ends in the parallel direction of the plurality ofterminal receiving chambers 5. Eachlance 7 is to be locked to the terminal received in eachterminal receiving chamber 5, and capable of moving toward the terminal unlocking direction by elastic deformation thereof. Each pair oflance unlock ribs lance 7, and protrudes in the first tool insertion holes 6, 6 adjacent to each other or in the firsttool insertion hole 6 and the secondtool insertion hole 6A adjacent to each other, - Two lance unlock
ribs tool insertion hole 6. One of the twolance unlock ribs lance unlock ribs adjacent lances lance unlock ribs lance unlock ribs adjacent lances lance unlock rib 8 and thetool pressing rib 9 are placed side by side in each secondtool insertion hole 6A. Thelance unlock rib 8 is one of a pair oflance unlock ribs lance 7 located at each of the ends in the parallel direction of the plurality ofterminal receiving chambers 5. Thetool pressing rib 9 is provided to a side surface of the each secondtool insertion hole 6A, and protrudes in the each secondtool insertion hole 6A. Theterminal extracting tool 20 is capable of being inserted in the first tool insertion holes 6, 6 adjacent to each other or in the firsttool insertion hole 6 and the secondtool insertion hole 6A adjacent to each other. - Therefore, even if the end part of the
insertion rod portion 22 is inserted in the secondtool insertion hole 6A located at each of the ends in the parallel direction D of the plurality ofterminal receiving chambers 5, the end part of theinsertion rod portion 22 is prevented from moving toward a direction away from thelance unlock rib 8 to be unlocked, by thetool pressing rib 9. This configuration can reliably unlock thelance unlock rib 8 to be unlocked which is placed in the secondtool insertion hole 6A located at each of the ends in the parallel direction D of the plurality ofterminal receiving chambers 5. - The
tool pressing rib 9 is mounted along the insertion direction f of the terminal extractingtool 20 in the secondtool insertion hole 6A. Therefore, an internal configuration in the secondtool insertion hole 6A located at each of the ends in the parallel direction D of the plurality ofterminal receiving chambers 5 is nearly the same as an internal configuration in the firsttool insertion hole 6 not located at each of the ends in the parallel direction D of the plurality ofterminal receiving chambers 5. - The
tool pressing rib 9 is mounted at a position where thetool pressing rib 9 faces thelance unlock rib 8 to be unlocked in the secondtool insertion hole 6A. Therefore, thetool pressing rib 9 reliably interferes in the adjacentlance releasing surface 24 of theinsertion rod portion 22. - Although the present embodiment is described above, it is not limited thereto, and may be modified within the gist of this embodiment.
